Definitions

  • the invention relates to environmental sensors, sensor units, sensor systems and/or sensing methods, particularly but not exclusively in agricultural or horticultural applications.
  • Environmental sensors are used in agricultural or horticultural settings in order to monitor growing conditions.
  • Known environmental sensors include e.g. temperature, humidity and soil moisture sensors.
  • Typical systems use individual sensors dedicated to sensing a single environmental condition. Existing sensors also suffer from difficulty in use and/or installation, with some sensors having high power requirements and requiring physical connection to a mains power source. Some sensors are arranged for wireless communication of sensed data. However, these sensors may have limited range and communication of data in a large area typically requires the use of separate communication repeaters.
  • JP6463866 B1 relates to a sensor apparatus for an agricultural greenhouse which can simply calibrate a CO 2 sensor.
  • the apparatus has a main casing and a sub casing suspended from the bottom of the main casing.
  • An internal space of the main casing is separated into an upper chamber (including a control part which processes a sensor signal) and a lower chamber which has a temperature/humidity sensor and a fan.
  • a CO 2 sensor, a power source and a CPU are housed in the sub casing.
  • a pair of air intake ports and an outlet port are disposed respectively at an opposing position of a wall closer to the lower chamber and a bottom wall of the chamber, and a fan is arranged in this area.
  • the CN204101758 U relates to a field microclimate automatic observation station with multi-data collection, multi-mode output of results and manpower saving.
  • the field microclimate automatic observation station includes a data acquisition unit which comprises a wind direction sensor, a wind speed sensor, a rainfall collection barrel, and a rainfall sensor.
  • an agricultural or horticultural environment multi-sensor unit as set out in claim 1.
  • the term 'about' or 'approximately' and grammatical variations thereof mean a quantity, level, degree, value, number, frequency, percentage, dimension, size, amount, weight or length that varies by as much as 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1% to a reference quantity, level, degree, value, number, frequency, percentage, dimension, size, amount, weight or length.
  • substantially' or grammatical variations thereof refers to at least about 50%, for example 75%, 85%, 95% or 98%.
  • the Applicant's sensor units, systems and sensing methods may be particularly suited to application in controlled agricultural or horticultural environments.
  • controlled environments may include, for example, greenhouses, indoor grow rooms, indoor farms etc.
  • the sensor arrangements may provide a detailed view of environmental conditions in the controlled environment.
  • the sensor units may include any combination of desired environmental sensors which includes at least an incident light sensor and a temperature sensor.
  • desired environmental sensors which includes at least an incident light sensor and a temperature sensor.

  • the sensor units may be arranged to communicate with each other and/or with a communications gateway, in order to provide robust and convenient communication of data from the sensors.
  • a mesh network may be implemented between the sensor units and the gateway. This may be achieved using any suitable wireless communications protocol.
  • Bluetooth may be used, which may provide easy configuration using a cellphone and the range necessary to operate in a large-scale growing environment.

  • Data may be gathered and provided to a cloud-based service which provides rich visualisations and insights to the user.
  • the sensor units may be arranged to automatically act as repeaters within the network when provided with an external power connection.
  • the sensor units may be arranged and/or controlled in order to limit or prevent undesirable interactions between sensors, which could impact on data accuracy.
  • the sensor units may operate with relatively low power requirements and may be either battery powered or may receive power from an external source (e.g. mains power). Measurements of many types are therefore provided by one low powered wireless device.
  • the measurements taken may include one or more of: temperature, relative humidity, solar irradiance, photosynthetically active radiation, air pressure, CO 2 concentration, and soil moisture. Other desired measurements may be added if required.
  • a lens arrangement may be used in order to pass incident light to the light sensors and in some embodiments to reduce the dependency of the sensor output on the light's angle of incidence.
  • one or more orientation sensors may be included to provide orientation data for the sensor unit. The orientation data may be used in correcting any sensor data based on known variations in the sensor data with orientation. This may be particularly useful in correcting data from the incident light sensor or sensors.
  • the sensors may include a carbon dioxide sensor. This sensor may be arranged to sense a concentration of carbon dioxide in the air. Infrared gas sensors may be suitable. Nondispersive infrared (NDIR) CO 2 sensors may be suitable. For example, a sensor from the CozIR ® -LP CO 2 sensor range may be suitable in some embodiments.
  • NDIR nondispersive infrared
  • the sensors include one or more incident light sensors. Any suitable ambient light sensor or other photodetector may be used. Photodiode sensors may be suitable. The incident light sensors may be sensitive across a desired wavelength range. The one or more light sensors may include either or both of: a solar irradiance sensor and a photosynthetically active radiation sensor. Photosynthetically active radiation is radiation used by plants in photosynthesis (usually considered to be in the wavelength range 400 to 700nm). In some embodiments OSRAM SFH2200 and/or SFH2240 sensors may be suitable, for example.
  • An optical arrangement arranged to pass incident light to the one or more incident light sensors may be included. This may be provided at the top of the sensor unit.
  • the optical arrangement may include a lens structure arranged to gather light from a broad range of incidence angles and pass it to the sensor(s).

This may be further improved by ensuring that the sensor unit is level.
  • One or more integrated orientation sensors e.g. accelerometer and gyroscope
  • the orientation sensors may also be used to monitor the angle of the product so that levelling errors can be detected.
  • this lens component may also provide a light pipe path from several LED lights inside the device to the outer surface of the housing to provide user feedback for installation, configuration and/or use.
  • the LEDs may provide feedback during installation and then be turned off to save power.
  • sufficient LEDs may be provided to allow feedback to be provided that: the sensor unit is running an installation test, the test was successful, communication failure (e.g. out of range), sensor failed test (preferably with a separate indication for each sensor within the sensor unit. Any combination of LED colours, solid light, flashing light, number of LEDs etc may be used to display this information.
  • the sensors may include a humidity sensor.
  • the sensor include a temperature sensor.
  • a single sensor measuring relative humidity and temperature may be used.

  • any suitable GPS sensor may be used, such as the Ubox GPS-SAM-M8Q.
  • Other positioning sensors may be used, e.g. based on local positioning systems.
  • users may enter sensor unit positions rather than relying on the use of a position sensor.
  • the sensors may include one or more orientation sensors, including e.g. 3-axis accelerometers.
  • the sensors are mounted within a housing.
  • a louvred housing is used, providing airflow through the housing (and to the sensors) without the need for powered flow devices such as fans.
  • the louvred design decouples the energy incident onto each louvre from the other louvres, making it difficult for thermal energy to travel to the inner areas of the sensor unit. This may be particularly advantageous in accurate measurement of temperature.
  • the temperature sensor may be protected from the influence of solar radiation which can skew the measurement upwards. This may be achieved by the louvred housing, and in addition a physical separation between the temperature sensor and at least some of the other sensors may be provided.
  • the temperature sensors are separated from the incident light sensors in order to provide accurate measurement.
  • incident light sensor(s) are located at the top of the sensor unit, with the temperature sensor located lower in the sensor unit (e.g. near the middle or the bottom of the sensor unit), isolating it from the effects of light heating the top of the sensor unit.
  • the louvred design decouples the energy incident onto each plate from the other plates making it difficult for thermal energy to travel to the inner areas of the device.
  • this structure promotes natural convection through the device allowing airflow while providing protection from water and sunlight.
  • the management of air flow through the sensor unit without the requirement of a separate fan unit allows the sensor unit to receive the required air across the sensors and reduces battery consumption.
  • a pair of C cell batteries are expected to last up to 12 months.
  • External or auxiliary sensors may be connected to the sensor unit.
  • an external soil moisture sensor may be connected to the sensor unit.
  • External sensors may communicate with the sensor unit via a wired connection, e.g. connected to an auxiliary sensor port.

  • External sensors may contain their own battery or external power connection, or may draw power from the sensor unit.
  • High quality and quantity of sensor data can be communicated via the network and uploaded to remote storage.
  • the sensor unit can be driven by an App or any other desired interface to give one or more indications of the microclimate/environment of the greenhouse or other growing environment.
  • the data may be stored for monitoring the environment history and/or for integration into control systems.
  • Visualisations and insights may be provided or displayed to the user.
  • User prompts or alarms may be issued via any suitable output or display device should any of the environmental conditions satisfy an alert condition (e.g. pass a threshold, fall outside an allowed range etc).
  • the prompts or alarms may be user-configurable via an app or other interface.
  • the sensor data may be used in a broader control system, in which environmental conditions are controlled in accordance with the sensor data.
  • Environmental conditions that may be controlled include: temperature, relative humidity, ventilation, solar energy, soil moisture and the like. Ventilation systems, watering systems, heating systems, cooling systems, shading systems, lighting systems etc may all be controlled based on the sensor data. Desired values or ranges for the environmental conditions may be set by a user, e.g. via an app or other suitable interface.
  • the sensors within the sensor unit may be controlled to gather data at staggered times, in order to reduce the peak power requirement of the sensor unit.
  • the carbon dioxide sensor may be operated during its own time interval as its power consumption is relatively high.
  • the sensor unit may be mounted in any suitable manner, and suitable fitting may be provided on the housing for pole mounting, hanging etc.
